石头剪刀布游戏重启分数未重置问题及while循环按需重复需求

问题描述 #

• 已实现石头剪刀布基础功能，但重启游戏时玩家分数（ps）与电脑分数（cs）无法重置为0
• 需要优化循环逻辑，实现按用户要求重复执行游戏循环

原始代码框架 #

x=1
i=1
ps=0
cs=0
while i==1:
    while x==1:
        print("First to 5 wins!")
        #print score
        score(str(ps),str(cs))
        #code for game and the outcomes
        #ending
        if ps!=5 and cs!=5:
            end=yesorno("Would you like to forfeit? (y/n)")
            if end=="y":
                print("You coward!")
                ngc=yesorno("Would you like to start a new game? (y/n)")
                ng=ngc.lower()
                if ng=="y":
                    i=2
                else:
                    i=1
                    x=2
                    input("press enter to exit...")
            
            else:
                i=1
        else:
            if cs==5:
                print("The computer won 5 to "+ps+"...")
                ngc=yesorno("Would you like to start a new game? (y/n)")
                ng=ngc.lower()
                if ng=="y":
                    i=2
                else:
                    i=1
                    x=2
                    input("press enter to exit...")
            else:
                print("The player won 5 to "+str(cs)+"...")
                ngc=yesorno("Would you like to start a new game? (y/n)")
                ng=ngc.lower()
                if ng=="y":
                    i=2
                else:
                    i=1
                    x=2
                    input("press enter to exit...")

解决方案 #

1. 分数重置问题修复 #

将分数变量ps和cs的初始化移到外层循环内部，每次启动新游戏时自动重置为0。

2. 循环逻辑优化 #

简化嵌套循环结构，用单循环配合条件判断控制游戏流程，避免多余状态变量的混乱赋值。

修改后的完整代码 #

while True:
    # 每次新游戏重置分数
    ps = 0
    cs = 0
    print("First to 5 wins!")
    
    while ps < 5 and cs < 5:
        # 打印当前分数
        print(f"Score: Player {ps} - Computer {cs}")
        # 此处插入游戏核心逻辑（玩家出拳、电脑随机出拳、判断胜负并更新分数）
        
        # 中途认输选项
        end = input("Would you like to forfeit? (y/n)").lower()
        if end == "y":
            print("You coward!")
            break
    
    # 游戏结束后判定胜负
    if cs == 5:
        print(f"The computer won 5 to {ps}...")
    elif ps == 5:
        print(f"The player won 5 to {cs}...")
    
    # 询问是否开启新游戏
    ng = input("Would you like to start a new game? (y/n)").lower()
    if ng != "y":
        input("press enter to exit...")
        break

修改说明 #

• 外层while True循环负责控制游戏的重复启动，用户选择不玩时通过break退出
• 每次进入外层循环时，自动重置ps和cs为0，彻底解决分数无法重置的问题
• 内层循环专注于单局游戏的进行，直到一方达到5分或玩家认输
• 移除了冗余的状态变量x和i，逻辑更清晰，避免赋值混乱
